Didn't GM try that with a V8? :-)

What's the difference between syphillis and an Oldsmobile diesel?

You can get rid of syphillis.

where do you find a 1kz-te in the us??

I got mine from www.jarcoinc.com. He imports the motor swap stuff and sells it. As for the who cares thing some of us want something with a good bit of power but its also nice to get 500 miles to a tank. The 1kz-te puts out 130hp and about 230lb ft. It moves along better than my V6 did. At least from what I can remember anyways. I like to have a truck that I can take off the road every now and then and not get stuck or break everything on it. But I still need something that I can travel back and forth the 900 miles to school and back with and not kill myself paying for fuel. Thats where this swap came in. I can't afford 2 vehicles nor the insurance on two. So gotta make one that does both things.

they are full of it. unless you mean imperial MPG, not US MPG...
the 2.7 comes in 95+ taco's, none of them get 27mpg... it will get slightly better than a 22re, not much better tho.
my 3.4 auto gets almost 21mpg in the summer.. in a big ass heavy limited 4runner 4x4....2.7 would prob be around 24mpg...

Weight is a huge factor in mileage and power. Putting a Corolla engine in a 4x4 pickup would make it about as slow as an old VW Bug and it would not get real good mileage because the engine would have to work hard just to make it go. As far as Camry engines, I kind of remember reading about a 5sfe swap in place of a 22R. If I recall correctly, you just need to drill a hole in the bellhousing or something, but I am not really sure.

Personally, I would not put a 5sfe in a pickup. My mom has a Camry, and it is a lot quicker than a truck, but it does not have the low end torque that the 22R has. The Camry gets about 24 MPG here in the mountains and my 4x4, which weighs a solid 1000 lbs more, gets about 21-22 MPG with the carbureted 22R under the same conditions. Basically, The 22R is a more efficient design than the 5s or 3s. My 4x2, which is probably about the same weight as a Camry, gets 29 MPG.

If I was going to do an engine swap, I would probably go with a 3RZ or a diesel and set it up to run on veggie oil.

Brake specific fuel consumption is the name of the game here. Unless some gas engine engine with good low-end toque also happens to have dazzling BSFC, then an engine swap won't accomplish much if anything. That's where diesels shine. They have tons of torque and great BSFC. The swap cost is often prohibitive, though, as well as the engine weight alone.

It takes a certain amount of power to maintain a given speed with a '91 4x4 with whatever tires, lift, etc. A larger engine will be at the mercy of frictional drag and design inefficiency while a smaller engine may have a hard time with the chassis drag and the old gearing.

Diesel offers 20%+ mileage increases yet it doesn't cost anywhere near 20% more than premium gas, so that would be the best place to look.

I'm one of those unbelievable cases of getting 32mpg, but my truck is 2WD, stock, and a 22RE. I managed my best mileage with no camper shell, either.

A big question, that I have is the gearing part. Right now with my 22re, 5 speed, and 31tires and at 70 mphs I am turning 3000rpms, which would be death for a diesel. So do you put in different gears or what?

hunter 4321

Could you change up the high range gear in the transfer case maybe? The transfer cases in these trucks are one to one i believe, if you could change that second number you would be in business.

I know this is all at the dreaming stage right now, but if the goal of the engine swap is to get better MPG, then you have already been told what you need to consider:-
1) you do want the most efficient engine that you can find (BSFC) and
2) you have to consider power to weight ratio.
An engine that gives you 30 mpg in a Corolla is not going to do the same in a 4wd. Toy.

As far as a bolt in swap the only one that I know of that does not require some form of fabrication is a 3.0 to 3.4 upgrade. For your truck, where it is a 22re the motor mount location is different that a V6 and it's different for a 2.7, so motor mounts have to be fabricated.
On the 7mge or 7m-gte you can use the forward motor mount location on the block and bolt them in to the 22re location but depending on the transmission you use your crossmember under the transfercase will require tweaking or out right movement.
5M-ge, 1Jz, 2jz, and 1uzfe all will require major fab work when it comes to engine, transmission, exhaust and radiator placement. Diesels Toy's where they are not available in North America as someone already alluded to the engine installation might be the easy part, trying to match it with the proper gearing could be the thorn in your side.
Don't get me wrong the challenge of putting an engine in a vehicle that wasn't there before and making it look like it came from the factory is the driving force for me, but I have yet to see one that didn't require you to think a little outside the box...and for some of us that is where our mind usually is anyway!

i would love to do a 1kt...3.0l deisel swap into a third gen 4runner......

bobby_duce

as for me i would love to do a diesel swap but getting the engine is the easy part, all the extra parts you need bring the cost up alot

watch this video, he says he gets 30 mpg

and heres one i like

I would love to do a diesel swap, but would also like to have a list of the parts needed to fit with what and so on.

birdduck

i gained 3-4mpg in the city and unsure on the highway for the reason that my trans was shot of my runner so it never saw the highway...
i did a 1uz swap and a 5speed conversion.
at 75mph i am at 3k rpms on 33's, an estimate of my mpg on my last drive was around 19mpg compared to the 12-15 the v6 got... not to mention i dropped about 150lbs of engine and gained 100hp and 90ft-lbs of torque...
i am into this swap around $1500, it took me around 4 months to complete working a few hours here and there when i could.

but this isn't a very fuel effective swap.... so yeah nm..

hross14

A sterling cycle engine would get you your best MPG's

Hey--just "Name Droping"---hhaaaa

87hilux7mgze

hmmm...pretty interesting claim, considering my dads 98 taco extra cab 4x4 with the 2.7 and a 5 speed, with 310k original miles gets a regular 26-28 mpg...his truck is bone stock and has never broken down, and hes had it since it had 80k miles on it. the only things replaced are the alt, starter, radiator, powersteering pump and carrier bearing. it has had one tune up including plugs, wires and fuel filter at 192k miles, that i did (i do all his maintenance).

could be altitude, could be fuel. all i know is, he is at 2500 feet, and buys 87 octane with 10% ethanol.

just saying...

Greg_Canada

2rz 2wd taco's get 22-25mpg... you're telling me his 4x4 3rz gets 26-28mpg....

Here is the EPA rating on that same truck:

1998 Toyota Tacoma 4WD
2.7 L, 4 cyl, Manual 5-spd

EPA Fuel Economy
Miles per Gallon
Regular Gasoline
17 Combined
16 City
20 Highway

Sorry i'd love to believe it, but unless it's 85 degrees and he drives downhill all the time... i cant believe it.... "ecomodders" i know with 2wd 2rz's squeak out 26mpg doing 50mph on highways and shuting off engines on downhills....

87hilux7mgze

not trying to shove it down your throat or say your wrong (not intentionally). im just saying what my dad gets. i can probably get some of his fuel books as well (he records mileage and has done so for the past 6 years)

when he was logging the lowest mileage he got was 23 mpg, driving around NW montana forest service roads.

anyway, with swaps, fuel mileage can be drastically different from epa estimates depending on your steady cruise rpm, vehicle weight, drag coefficient and gearing.

considering the average mpg of the mkIII supra (turbo, about 22-24 hwy, 16-18 in town/naturally aspirated 25-28 hwy, 17-20 in town), it wouldnt seem possible for someone to do a 7mge swap into a pickup, put 35's on and fully locked 5.29's with a 6 inch total lift and SAS to plug 19-21 mixed driving. but they do.

neway, cheers, if you want the most fuel efficient swap, diesel or propane (just cause of the cost of gas)
